  • Section: GPU and LPU Integration: Attention FFN Disaggregation (AFD)
  • Line hint: 125

Context Before

Comparing the two operations, we see attention is stateful due to dynamic KV cache loading patterns, whereas

Evidence

FFN is stateless since the computation only depends on the token inputs.

Context After

Thus, we disaggregate the computation of attention and FFN. We map attention computations to GPUs, which handle dynamic workloads well. For FFNs, we map them to LPUs, since LPU architecture is inherently deterministic and benefits from static compute workloads.

② Atomic Claim

FFN 是 stateless,因為其運算只依賴 token input。
